Now that SQLite, the back-end storage for Places, is going to support full-text indexing (http://www.sqlite.org/cvstrac/wiki?p=FullTextIndex), we can significantly enhance Firefox's search capabilities by searching more than titles and URLs. Among the design questions to be considered are what to index, how and where to display the results, and what options to support. This bug is intended to serve as both a tracking bug for individual portions of the work and a discussion point (in addition to mozilla.dev.apps.firefox) for design ideas.
Note http://skrul.com/blog/projects/xpclucene/ , a CLucene-based solution, which is less elegant than using sqlite, but still mentioning.
I'm happy to see mozilla starts hacking natural language processing. Then we'll really go with SQLite? I'm not too sure yet, but I'm afraid that full text indexing in SQLite does not work nicely with CJK languages. 中文と日本語では、単語が空白で区切られていません。 BothinChineseandJapanese, wordsarenotseparatedwithwhitespaces. To slove this probelm, Lucene uses "Tokenizer"s for specific languages. http://lucene.apache.org/java/docs/api/org/apache/lucene/analysis/class-use/Analyzer.html http://lucene.apache.org/java/docs/api/org/apache/lucene/analysis/Tokenizer.html However, CJKAnalyzer sucks. And I don't believe SQLite will implement anything better than that, in a short period. On the other hand, I guess commercial search engines such as Google and Yahoo are doing some kind of linguistic approach, especially Morphology, though I don't know exactly what they are doing. http://en.wikipedia.org/wiki/Morpheme http://en.wikipedia.org/wiki/Conditional_random_field Unless we'll be able to tokenize input properly, this feature will never reach the product-level quality. Anyway, the backend is not just a wrapper of a SQL database. At least we should support lang-dep-tokenizer switching.
I doubt any CJK tokenizer will be included with SQLite by default, but the text-indexing system is designed to allow developers to plug in custom functions. The trick will be finding (or writing) good ones.

I want the words I type in the address bar to match the title of the pages in my history. I believe that Firefox does that now. I don't want them to match the text content à la Chrome, because it is too heavy, slows down everything. But being able to search, in the History panel and window, the text content of the pages would be great !
